 On NetBSD-current - after adjusting the include from <editline/readline.h>
 to <readline/readline.h> it seems that running that there is a
 "\n".
 
 On which NetBSD version this happens?
 
 If it's not on NetBSD and there are any $NetBSD$ RCS Id in the
 editline source code and headers or similar please share them: it
 can help to possible bisect the problem.
 
 
 Thank you!
